The adult cavus foot.

Cavovarus deformity can be classified by the severity of malalignment ranging from a subtle and flexible to a severe and fixed cavovarus deformity of the foot.In the mild cavovarus foot, careful clinical assessment is required to identify the deformity.Weight-bearing radiographs are necessary to indicate the apex of the deformity and quantify the correction required.Surgery is performed when conservative measures fail and various surgical procedures have been described, including a combination of soft-tissue releases, tendon transfers and osteotomies, all with the aim of achieving a plantigrade and balanced foot.Joint-sparing surgery is the best option in flexible cavovarus foot even in Charcot-Marie-Tooth (CMT) disease (peroneal muscular atrophy).Arthrodesis is indicated in severe rigid cavus foot or in degenerative cases.
